7 title: ARM Versatile FPGA IRQ Controller
10 - Linus Walleij <linus.walleij@linaro.org>
13 One or more FPGA IRQ controllers can be synthesized in an ARM reference board
14 such as the Integrator or Versatile family. The output of these different
15 controllers are OR:ed together and fed to the CPU tile's IRQ input. Each
